Having a huge issue with my 2000 blazer. 6months ago the rotor, cap, coil, plugs, and wires were replaced. Two weeks ago driving 65mph down the interstate it Just dies. No warning at all. Will crank fine, but no start. Tested fuel pump, good psi there. Changed fuel filter, MAP sensor, cleaned MAF sensor, replaced cap and rotor. Replaced coil again. Car started up a few times, then died. Now it has gone back to crank no start and no spark coming out of the New coil. Someone please help!

 

Is the PCM triggering the coil to send a spark? If not figure out why, fix that, and it will start.

 

did you get an engine code? sounds like mine last week , was the camshaft sensor
